The sub-menus are described in the following section. To select a particular menu press the plain grey button to the right of it. For full instruction on how to perform a calibration see The following describes the available settings for each gate with the differences between the gates stated. Gate 1 is used to select the reference echoes. See A-Cal on page for a full procedure.
The actual distance to the first or thinnest reference echo in DIST1 the calibration block. Select the menu at any time by pressing the button. This feature is used when testing pipes and other curved surfaces. In order for the Once drawn, the DAC curve acts as an alarm threshold level for the gate where the level varies to match the attenuation and field characteristics of the transducer and test material combination.
Used to select the reference reflector type: Flat Bottom Hole It provides a convenient method to automatically calculate the Indication Rating as defined in the code. The AWS The items in this section allow the user to configure features such as units, display preferences, language, back wall echo attenuation BEA , print options, proportional output configuration and date and time settings.
The built in languages are selectable at time of ordering the Sitescan Allows the user to display a vertically compressed A-Scan in Please note that this requires a printer with a USB port from the Sonatest certified list of printers. Two outputs are provided. The outputs are active when the associated gate is triggered and are updated at the PRF. These menus allow the user to save panel settings, A-Scans and thicknesses as well as recalling an A-Scan to be used as a reference.
Pressing the grey Before a waveform can be recalled, it must be stored in an A-LOG location as described above. In this mode location and historical thickness data can be downloaded to the Sitescan from a computer, a fixed series of four notes can be added to a location. Then select the EDIT box in the menu and notice that the window shown below overlays the display area. Exit the Notes window to change to another menu. The following shows a completed notes window: 4.
Page Flaw Testing Fabricated discontinuities must also be placed near the front and back surface of the calibration block to verify resolution of the transducer and instrument setting combination. Finally, it is necessary to establish the proper calibration of the Sitescan in order to assure reliable flaw detection. Page Flaw Testing Calibration The essence of this calibration is to set the pulser, amplifier and gate parameters to provide the necessary sensitivity and resolution.
The Sitescan has an automatic calibration technique that sets the necessary parameters by using a calibration block that has known thicknesses; The distance between the echoes is shown in the G-G measurement at the bottom of the display in this case It is unlikely that the value will be exactly correct as the velocity of sound in the material will not match one of the preset values. The distance measurement is shown at the bottom of the display in this case From the menu adjust the value until the correct distance is shown as ZERO below: As a final check move the gate across the other echoes to ensure that the correct distances are shown; For weld inspection using an angle beam transducer, follow the instructions in Weld Inspection Using Trigonometry Mode on page Establish the basic calibration of the Sitescan using the desired transducer and the proper reference block.
From the menu, select the feature. These additional, automatically generated, reference curves provide a method for helping to evaluate discontinuities smaller than those in the reference block. Page Weld Inspection Using Trigonometry Mode The trigonometry mode provides a convenient method for measuring the location of discontinuities when inspecting welds with angle beam transducers.
Essentially, the trigonometry mode uses the thickness gauging features of the Sitescan to calculate the surface distance and depth to a discontinuity from the actual beam path measured. This is accomplished by calibrating the trig mode with the actual refracted angle of the transducer being used. To calibrate and use the trigonometry mode, follow the following instructions: 1. To set up the AWS measurements, perform the following: 1.
